1. What a meter sends over cellular
Smart metering reads water, power, gas, and heat meters automatically over NB-IoT and LoRa, instead of sending someone to the door. It supports AMI (advanced metering infrastructure), tiered tariffs, alarms, and remote valve control. AMI covers the meter, the network, and the reading platform, with two-way communication, demand management, and protocols such as DLMS/COSEM. NB-IoT reaches far, punches through walls, and draws little power, which fits weak-signal spots such as meter pits and stairwell cabinets. SimtoLink supplies NB-IoT and 4G to water, power, gas, and heat utilities, with a data pool, batch activation, and an API into the reading platform.
2. Homes, commerce, and irrigation
The estate covers residential meters, commercial and industrial meters, and agricultural irrigation meters. How often a meter reports, whether it has a valve, and what it costs differ by type:
Smart water meters
An NB-IoT water meter reports daily or monthly use, spots leaks, and can close the valve from afar. Underground pits and stairwell cabinets are often weak on signal. NB-IoT punches through and covers widely, at about 1–3MB a month.
Smart electricity meters
A power meter needs frequent reads, every 15 minutes or every hour, plus a load curve and demand data. Choose NB-IoT or 4G from how often it reports. Typical use is 2–10MB a month.
Smart gas meters
A gas meter needs safety certification, a remote valve, and an alarm for unusual use. NB-IoT fits residential meters. Commercial and industrial meters can use 4G when they report more often.
District-heating meters and heat meters
The heating season needs usage reports, room-temperature readings, and remote adjustment. NB-IoT is low cost and lasts, which fits a district-heating community rolled out in volume.
3. What the meter link has to cover
- Reach and penetration: Meters sit in basements, pits, and stairwell cabinets, where the signal is weak. NB-IoT punches through and covers widely, which fits a large rollout.
- Low power and a long life: Some meters run on a battery. NB-IoT can last more than 10 years. Where a valve has to answer at once, use 4G.
- Reads that survive a drop: Usage data is what the bill is built on. Cache locally while the link is down and send the gap after it returns, so the read still lands.
- Security and compliance: Sessions need TLS/SSL and a private APN. Usage data has to resist tampering, in line with metering and billing rules.
- A flexible API: Connect to the reading platform, the billing system, and the payment-control system, so AMI, tiered tariffs, and remote valves close the loop.
4. Which SIM fits which meter
How often a meter reports, whether it has a valve, and what it costs differ by type, and so does the site. Use the table as a starting point:
| Use | Recommended network | Why it fits |
|---|---|---|
| Residential water and gas meters | NB-IoT | Infrequent reads, pit penetration, and low cost |
| Smart electricity meters | NB-IoT / 4G | Load curves and frequent reads can use 4G |
| Commercial meters and remote valves | 4G | Live valve control, frequent reports, and demand data |
| District-heating meters and heat meters | NB-IoT | Infrequent reports in the heating season, at low cost |
5. How much data a meter uses
One meter typically uses about 1–5MB a month, depending on whether it reports daily, weekly, or monthly, and whether it also sends valve events. An NB-IoT data pool can be shared across tens of thousands of meters. Keep 20%–30% spare.
6. Security for usage and billing
Usage and billing data are sensitive, so treat the link as medium security. Sessions need TLS/SSL, a private APN, and an IP allowlist. SimtoLink provides the private APN and completes real-name registration for the SIMs.
7. What SimtoLink would put in the meter
For water, power, gas, and heat meters that report infrequently and have to stay cheap, use an NB-IoT SIM. For frequent reads, such as on a power meter, use a 4G IoT SIM. NB-IoT’s reach fits weak-signal pits. SimtoLink plans for 99.9% network availability, a data pool, and an API into the reading platform.
8. Rolling meters out across a district
Take a metering rollout through these stages:
Pick the SIM by meter type and how often it reports, and check NB-IoT coverage in the target community and in the pits. Set the APN and IP allowlist, and alert at 80% of the data allowance. SimtoLink stays with the project from the first meters through the wider district. Contact us for a plan built around those meters.
